Materials & Tolerances

We work with a diverse range of materials to match the specific requirements of your application, considering factors like wear, thermal expansion, chemical resistance, and weight. Common materials include:

• Tool Steels: For high wear resistance and durability in demanding machining applications.
• Aluminum Alloys: Offering a balance of strength, machinability, and weight, often anodized for surface hardness and corrosion resistance.
• Stainless Steels: For applications requiring corrosion resistance, such as medical or cleanroom environments.
• Engineering Plastics (e.g., Delrin, PEEK, UHMW): For non-marring contact with delicate parts, electrical insulation, or specific chemical resistance.
• Composites: For lightweight, high-strength applications.

Our in-house capabilities allow us to achieve tight manufacturing tolerances, typically down to ±0.001 inch (±0.025 mm) or better, depending on material and geometry, ensuring that your fixtures precisely meet the demands of your production processes.

Lead-Time Considerations & Maintenance

Lead Time: The lead time for custom fixtures is highly dependent on design complexity, material selection, and manufacturing processes required. Simple designs can be prototyped rapidly, while complex, multi-component fixtures may require several weeks for design, simulation, manufacturing, and validation. We work with your project timelines to provide realistic estimates and prioritize critical path items.

Maintenance: Proper maintenance is crucial for extending the lifespan and ensuring the continued accuracy of your custom fixtures. We recommend regular inspection for wear, damage, and accumulation of debris. Depending on the material and application, periodic cleaning, lubrication, or recalibration may be necessary. Our team can provide guidance on best practices for fixture care to maximize their total cost of ownership and maintain production continuity.

Frequently Asked Questions

What kind of information do you need to design a custom fixture for my product?

To design an effective custom fixture, we typically need 3D CAD models of the part(s) to be held, details about the manufacturing process (e.g., machining, assembly, inspection), desired tolerances, production volume, and any specific environmental or material requirements. Understanding the operational context helps us optimize the design.

How long does it take to get a custom fixture designed and manufactured?

The timeline varies significantly based on the complexity of the fixture. Simple designs might take a few weeks, while more intricate, multi-component fixtures requiring extensive engineering and specialized manufacturing processes could take longer. We provide detailed project timelines after an initial design review.

Can you help us with design-for-manufacturability (DFM) advice for our parts, specifically related to fixturing?

Absolutely. Our engineering team offers DFM advisory services. We can review your part designs and suggest modifications that will not only simplify manufacturing but also optimize them for more efficient and robust fixturing, ultimately reducing production costs and improving quality.

What materials do you typically use for custom fixtures?

We select materials based on the application's specific needs. Common materials include various grades of tool steel for durability, aluminum alloys for lighter weight and machinability, stainless steels for corrosion resistance, and engineering plastics for delicate parts or electrical insulation. We'll recommend the best material for your specific requirements.

Do you offer maintenance or repair services for the fixtures you produce?

While we don't offer ongoing maintenance contracts, we can provide guidance on best practices for fixture care to maximize their lifespan. If a fixture we produced requires repair due to manufacturing defect or wear, we can assess the situation and discuss potential solutions.

How do your custom fixtures improve overall production efficiency?

Our custom fixtures are designed to improve efficiency by ensuring precise and repeatable part placement, reducing setup times, minimizing manual adjustments, and enabling faster cycle times. This leads to higher throughput, less scrap, and more consistent product quality, ultimately lowering your total cost of ownership.
